bigger the plant bigger the yield?

My plant is 17" tall and roughly about 8 week old, im waiting for it to hit 2' before i stick her in flowering mode, will i get more of a yield be waiting for it to grow bigger in veg mode?
cheers

Obviously. Height usually doubles in flowering, if it matters for space. If you only have one plant your not guarentteed a female so good luck!

No i was very lucky with my first eva plant shes a she i got a room with a 7' high roof so i might even let it grow bigger in veg mode maybe 3' before flowering

They don't always double in height, sometimes they triple in size. you might wanna rethink the 3' tall thing. DO you have enough light to flower a 4-6 foot tall plant, your gonna need around a 600 watter to get the light through the canopy. Otherwise a 3' tall plant can use a 400 watt HPS.

i currently have 12 18 watt cfls 6 are on the plant in question and the other 6 are in my home made hood but if needed i can remove em from hood and put em all on my girl 6 above n 6 rigged lower arround the plant
